Skip the wet. They will have better dental health with dry only. Check the back of dry dogfood bag of your choice for how much. I suggest Iams. Their motto back in the 80's was LESS IN LESS OUT. That sold me.

Ditto on the skip the wet. They need the fiber & it's healthier for their teeth.

Here's an excellent link to learn how to pick out a good food. I've researched this for years & I can instantly recognize bad ingredients. I feed mine one of the Wysong ones. I've had healthy dogs w/healthy hair for years & years because I've always paid attention to ingredients. The vets I go to frequently comment on their shiny hair.

Reason being, it's easier to give them medications when needed. Not sure how much to feed your size dog , but we feed our 65 pound dog at dinner time only on a 1/2 can and a full supply of dry daily, never mixing the two, with plenty of fresh water.
